Specification of Letters iatent. I Pat nted Feb 29, 1916 Application filed September24, 1912. Serial No. 722,034.

To all whom it may concern:

Be it known that I, WALTER J McVIoKnR, of -Minneapolis, 'I-Iennepin county, Minnesota, have invented certain new and useful Improvements in Frames for Traction-Engines, of which the following is a specification. 1

The objectnof my invention is to provide a strong, substantial frame to support the engine and operating mechanism of the machine. 1 r

A further object is to'provide a frame of comparatively simple construction and one which will be extremely rigid in proportion to its weight and dimensions.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a side elevation, partially in section, of. a traction engine embodying my invention, Fig. 2 is a perspective view of the frame, looking toward the rear end thereof, Fig. 3 is a perspective view, looking toward the side of the machine.

In the drawing, 2 represents the rear axle, forward axle having carrying wheels 5. .6 is the engine, supported upon a girder-built frame which forms the'subject matter of my invention and which I will now describe in detail.

The main frame,

forward and rear cross bars 8 and 9 and an intermediate bar 10, all of said bars being securely riveted to the flanges of the channel bars. The under frame consists preferably of angle bars 11 having their rear portions parallel substantially with the channel bar 7 and connected therewith by upright angle bar braces 12. The forward portions of the angle bars 11 are upwardly turned and have their forward ends rigidly secured to the channel bars 7 Between the upper and under frames I provide steel plates 13, riveted to the said frames and forming a plate girder on each side of the frame. Cross braces 14 are provided between these plate girders and suitable braces 15 conor upper portion, consists of side rails 7 of channel bar, having nect the'opposite horizontal flanges of the angle bars 11.

The arrangement of braces-between the girder plates provides for an extremely rigid frame to which the motor transmission system and the radiator are bolted. A bolster 16, triangular in form, is secured to the forward portion of the girder frame, with its lower endresting onthe forward axle. An angle bar 17 is provided with a series of holes 17 therein and with braces 18 which extend forwardly and also have holes therein to receive bolts 19 mounted in a draw-bar 20. This draw-bar is attached to one of the cross braces of the frame by a spring connection 20. The angle bar 17 and the bars 18 form a detachable plow hitch, the holes 17 allowing a series of plows to be connected to this angle bar in the rear of the machine.

Rails 21 are secured to the girder plates and extend rearwardly therefrom and rest upon a cross bar 22. Upon these rails 21 a platform 23 for the operator of the machine is mounted.

The rear axle 2 passes through openings 24 provided in the girder plates, as shown in Fig. 1.

The gasolene tank of the power plant may.

be secured to the girder frame in any suitable manner, but I prefer to provide straps of the channel rails. By tightening the nuts on the ends of the straps the tank may be rigidly secured to the top of the frame.

' I claim as my invention 1. A traction engine frame comprising upper parallel side rails, lower parallel side rails having upwardly turned forward portions secured to said upper rails, upright braces interposed between the rear portions of said upper and lower side rails, girder plates secured to said side rails and said braces, cross bars interposed between the opposite side rails and between said girder plates, a rocker forward end of said side rails, and forward and rear axles having carrying wheels supporting said rocker and the rear portion of said frame.

2. In a traction engine, a, girder-built frame comprising upper and lower members, the forward portion of said lower member provided at the sald being upwardlyturned and connected to upper member, the rear portions of 3. A built-upgirder frame comprising' an upper member, a lower member having its forward portion upwardly turned and secured to said upper member, girder plates having their upper and: lower portions see cured respectively to said upper and lower members, braces between said girder'plates, a bolster arranged beneath the forward portion" of said members, a forward axle wvhereon'said bolster is mounted, and a rear axle projecting through openings provided in the rear portion of said girder plates.

4. In a traction engine, a girder-built frame having asubstantia'll'y fiat top forming an engine bed, a bolster arranged be neath: the forward-portion of said frame, the rear portion of said girder-built frame having openings therein, and a rear axle projecting through said openings.

5. A traction engine frame comprising upper parallel j-ohannel bar rails, lower parallel angle bar railshaving their rear portions parallel substantially with said 7 channel rai'l's'and their forward portions upwardly turned and secured to said chan: nel rails, girder plates extending from end to end oflaaid- Upper and lower rails and secured thereto, the rear portions of said girder plates havingbearings for the rear v axle therein and the forward portion of said channel bar rails-V having a rocker de pending therefrom, and suitable 'bracesins V terposed between the opposite rails and girder plates. 7 c I In. Witness whereof, I have hereunto setmy hand this-18th day of September, 1912'.
